Tagetes erecta
Easy · Beginner friendlyAbout Mexican Marigold
Tagetes erecta, the African marigold (actually from Mexico), produces large, pompom-like flowers in rich yellows, oranges, and creams on sturdy 60–90 cm plants. One of the easiest annuals from seed, it blooms from early summer until frost. The pungent foliage deters many garden pests. In Mexico, marigolds are the iconic flower of Día de los Muertos, creating golden paths to guide spirits home. Commercial varieties like 'Inca' and 'Discovery' produce uniform plants for mass bedding. Marigold extract (lutein) is the primary commercial source of this important eye-health supplement.

History
Tagetes erecta is native to Mexico and Central America, where it was cultivated and culturally important long before European contact. Its Nahuatl name is cempasúchil ('twenty-flower' or 'many-petal flower'), and it remains the defining flower of Mexico's Day of the Dead (Día de los Muertos) celebrations on November 1–2: altars are piled with its vivid orange-yellow flowers, and petal paths are laid from cemetery gates to family graves to guide the returning spirits of the dead home. Spanish colonizers took it to Europe in the 1500s, and the species now grows as a crop throughout India, China, and South Asia, where it is also the source of yellow-orange carotenoid pigments used commercially in chicken feed (to deepen egg yolk color) and in fabric dyeing.
Non-toxic to pets. Spanish explorers brought it to Europe in the 1500s, and it reached Africa via Portuguese traders — hence the misleading common name.
In Mexico, the Día de los Muertos celebration uses over 15,000 tonnes of marigold flowers annually — the bright petals are believed to attract departed souls with their color and scent. India is the world's largest marigold producer, growing them for temple garlands, wedding decorations, and the industrial extraction of lutein, a carotenoid pigment crucial for eye health.
